There is so much information on there it will make your head spin. These 20,000 members have extreme knowledge on the Dodge Ram, all the way from old ones to the new '15's.
I have a 2013 1 ton dually with the 3:42 gears with the Aisin Tranny that is rated at almost 24,000 lbs. If you were to get a dually with the same tranny and 4:10 gears - towing is at 30K.
Put a set of Firestone Ride Rite air bags under the truck you have, tow the new camper anywhere you want to go. The dually will give you more stability since you have training wheels for the added support. Just remember, 2 extra wheels, heavier truck, extra maint. and DEF needs to be kept full on every oil change. You will love hte new trucks even from a 2011 to a '13 / '14 as I traded in my '05 for a '13. 350 HP with 850 ft. lbs. of torque. Yeat, I like it very much.
Enjoy and be careful on your travels.
